No Smoking Map

Privacy Policy

Last updated: July 30, 2026

What is stored

  • Sign-in uses OAuth only (Google/Telegram) — the app never sees a password
  • Google sign-in (optional): name, email, and profile picture from your Google account
  • Telegram: your display name and Telegram user ID (see "How your account is created" below)
  • Reviews you submit: smoking status, optional comment, and timestamp
  • Venues you add: name, location, and address

How your account is created

When you open No Smoking Map inside Telegram, an account is created for you automatically so the app can save your reviews and favorites. This account holds only your Telegram display name and Telegram user ID, and no email address. There is no password — you always sign in through Telegram (or Google), so the app never sees one. If you also sign in with Google, your Google name, email, and profile picture are added to the same account.

Local storage

Preferences are stored locally on your device (not on the project's servers):

  • Language preference
  • Theme preference (light/dark)
  • Geolocation permission state

Analytics

No Smoking Map uses Vercel Analytics for aggregated, anonymous usage statistics. It does not use cookies, does not collect personal data, and does not track individual users.

Third-party services

  • Mapbox — map tiles and geocoding. Subject to Mapbox Privacy Policy.
  • Google — authentication. Subject to Google Privacy Policy.
  • Vercel — hosting and analytics. Subject to Vercel Privacy Policy.

Deleting your data

To delete your account, — just ask us to delete your account. When we process it, the following is permanently removed:

  • Your account and sign-in details
  • All reviews you have written
  • Your saved favorites
  • City and data-source suggestions you submitted
  • Feedback messages and any reports you filed

What stays on the map

Venues you added remain on the map so others can still find them, but they are no longer linked to you — your authorship is removed.

You don't have to delete everything. You can also — for example, a single review — either on their own or together with an account-deletion request.

To run the app (and only for that purpose), your data is shared with the providers of the services it relies on (hosting, database, maps, sign-in). No Smoking Map does not sell your personal data.
